All Status Inputs are common to an internal 24V DC source on the SCOM terminal. Status
input terminals S1 and S2 are positive polarity and SCOM is negative polarity.
For optimal EMC performance, we recommend wiring the status inputs by using shielded
cable, Belden 8771 or equivalent, with the cable shield grounded at both ends where possible.
Status Input Connections
Applied resistance versus status state
• Condition 1 is 3.5 kW or less = ON
• Condition 2 is 5.5 kW or greater = Off
Isolation Voltage is 500V status input to case and 500V status input to internal digital
circuitry.
Relay and KYZ Outputs
Control Relay Connections on page 36 shows the Form C relay output connections and an
example of customer wiring to a supply voltage and two loads. Terminal R11 is the common
connection, R14 is the normally-open connection, and R12 is the normally-closed
connection. You must supply the wetting voltage and overcurrent protection for the circuit
connected to the relay output.
Refer to Specifications on page 56 for further information.
TIP
Status Input S2 can be configured for external demand pulse input. See the
Powermonitor 3000 User Manual, publication
1404-UM001 , for more information.
